A pool basketball hoop from a trusted brand like Huffy is great both as a floating basketball hoop for pool use, above ground or inground usage. The basketball hoop for pool fun is a cheap way to add more interest to your swimming pool.
I have visited the manufacturer's website and I am unable to find any information on the diameter of this basketball. the only information they provide is that it is a replacement basketball for their Pool Shot basketball lines.
Most people choose portable basketball hoops for swimming pools. They're a lot more practical, and cheaper to purchase compared to an in ground hoop. After all when you're outside swimming, you're just looking to have some fun. You don't necessarily need a professional basketball hoop. Something that's just sturdy, and reliable to play on is good enough. Besides you can always move a portable hoop if it is in your way. You don't get that luxury with in ground hoops.
Wall mounted basketball hoops for pools are pretty rare. However, if your swimming pool is close enough outside by your house, garage, porch or any other exterior wall where a hoop can be mounted on, then you could decide just to purchase a wall mounted basketball hoop. I generally really love wall mounted basketball hoops a lot. But for a pool hoop it just doesn't seem as practical as an in ground or portable basketball hoop. A wall mounted hoop more than likely won't be as close to the pool (after all it needs mounted on a wall) making it a bit awkward to play on.
